Definitions

  • the present invention relates to an arrangement comprising a channel section and a nut for location therein as recited in the preamble of claim 1.
  • Nuts of this type are known, for instance from US-A-3 483 910. Before the screwing in of the bolt, such nuts are held in the channel section by means of a helical spring on the top side of the nut. Such nuts are difficult to remove from the channel section once they have been brought in place and, in addition, are difficult to displace in the channel section, for instance for adjustment to the desired bolt position. Installation of the nut in the channel section often requires two hands and when the channel section is used for ceiling attachment, danger to the worker may result if he has to stand on a ladder without being able to steady himself with one hand during the installation.
  • the object of the present invention is to provide an arrangement of said type, which does not suffer from the above deficiencies and drawbacks, and which at the same time is simple both to use and to manufacture.
  • the design of the nut according to the invention with a gripping means permits very simple insertion of the nut in the channel section.
  • the clamping device of the gripping means holds the nut in place, both before and while the bolt or the like is being screwed in.
  • the clamping device permits relocation of the nut in the channel section in a simple manner without the use of tools or other aids and, besides, the clamping device will provide a feelable indication of the location of the nut during poor lighting conditions.
  • the gripping means permits removing the nut from the channel section in case this should be desirable. All of this may be accomplished by the use of one hand only.
  • a portion of a channel section 1 is shown, having a generally circular cross section and a longitudinal opening 2 having limiting edges 3 and 4.
  • the limiting edges are bent outwards in opposite directions so as to form longitudinal flanges.
  • US-A-4 389 830 which is hereby incorporated as reference.
  • Fig. 1 further shows a nut 5 according to the invention, in this case comprising a rectangular main body 6 provided with a threaded hole 7 and a gripping means generally designated 8.
  • the gripping means is comprised by a bent metal wire and has at its one end a clamping device 9, generally in the form of a U-shaped loop.
  • One leg of the loop 9 is connected to the main body 6 of the nut by means of a portion 10 of the metal wire extending generally perpendicular to the axis 11 of the threaded hole 7 of the nut.
  • the loop or the clamping device 9 of the gripping means 8 is grasped and the main body 6 of the nut is introduced sideways through the opening 2 to the position shown in Fig. 1, the thickness of the main body being slightly less than the width of the opening 2.
  • the loop 9 is subjected to a torque about an axis parallel to the axis 11 of the hole 7, so that the connecting portion 10 is bent resiliently and the main body 6 of the nut is pushed down to longitudinal contact with the bottom of the channel section.
  • the loop 9 is subjected to yet another torque, but this time with the connecting portion 10 as the axis, so that the main body 6 is rotated about 90° to the position shown in Figs.
  • the loop 9 extends somewhat out from the channel section. This extending part of the loop may be gripped and used to slide the nut in the channel section to the desired position upon its introduction into the channel. The loop may of course also be used to remove the nut from the channel section whenever desirable.
  • Fig. 4 shows an exemplifying embodiment of the nut according to the invention, where the main body 6 is provided with longitudinal serration 14 on the longitudinal edges.
  • Fig. 5 a simplified embodiment of the gripping means 8 is shown, its U-shaped loop having straight legs without any indentations. This embodiment makes it simpler to twist the nut somewhat after its introduction into the channel section, which may be desirable if the bolt or the like to be fixed in the hole 7 cannot be introduced exactly at right angles into the channel section.
  • Fig. 5 also shows an advantageous embodiment of the main body 6 of the nut. Its top surface 15 is curved in order to approximately fit the internal shape of the channel section in order to form firm engagement even when the bolt position is somewhat askew. Furthermore, the top surface of the nut has a conical portion 16 continuing into the threaded hole 7 of the nut, which also contributes to ease the introduction of a somewhat canted bolt.
  • Fig. 6 an embodiment is shown where the main body of the nut has angled longitudinal edges 17 in order to provide a larger abutment surface with the inside of the channel section.
  • Fig. 7 shows an embodiment where the main body 6 of the nut is provided with three adjacent threaded holes 7. Such an embodiment is advantageous for applications where supporting brackets or the like, which are loaded in a direction parallel to the longitudinal direction of the channel section, are to be attached to the channel section.
  • the gripping means 8 itself may advantageously be made from resilient steel wire, for instance piano wire, which is spot welded to the main body of the nut.

Abstract

Un écrou destiné à être logé dans un profilé en U ouvert (1) comporte un corps principal (6) pourvu d'un trou fileté (7) et un moyen de fixation (8) assemblés sur le corps principal (6). Le moyen de fixation (8) comprend un dispositif de serrage (9) qui coopère avec des rebords (3, 4) limitant une ouverture longitudinale (2) dans le profilé en U. Lors de l'insertion de l'écrou dans le profilé en U, le moyen de fixation est soumis à un couple autour de deux axes généralement orthogonaux, et lorsque l'insertion est achevée, l'écrou est maintenu en position correcte grâce à la coopération d'un blocage de forme et/ou de frottement entre les rebords (3, 4) limitant l'ouverture (2) et des endentements (12, 13) des branches d'une boucle (9) en forme de U constituant le dispositif de serrage.
